No, it wasn't. Unless you meant predictable as in going by the clues. But if you meant it in the other way: What would have been predictable is if they were both contract killers. We only figured out he was the head of the organization because the clues lead us that way. I mean the only reason he could have been able to accept the package when Siyeon wasn't present obviously was because he was the head of the organization.

Taekyung is Siyeon's employer, he's the head of the organization for which Siyeon works. During one of his missions Siyeon will be taken by Taekyung and his men, but they will cover up his head and when they take it off, Siyeon and Taekyung will be standing face to face. I wonder what happens next!
